PETER A. SOLEM, OF CINCINNATI, OHIO, ASSIGNOR TO J. A. FAY & EGANCOMPANY, OF CINCINNATI, OHIO, A CORPORATION OF VEST VIRGINIA.

WOOD-PLANING MACHINE.

To all whom it may concern Be it known that I, Perm: A. Sonmt, a citizenof the United States, residing at Cincinnati, in the county of Hamiltonand State of Ohio, have invented certain new and useful Improvements inNeed-Planing Ma chines, of which the following is a specific. tion.

My invention relates to wood-planing machinery, and is principallyapplicable to wood-planing machinery employing a horizontally disposedcutter-head arranged to operate on the upper side of stock, whether saidcutter-head is the sole cutter-head in the machine, or othercutter-heads operating for instance on the bottom or on one or moreedges of the stock, are employed.

It is the object of my invention to provide new and improved relation ofmeans whereby the chips caused by the cutter-head are removed; furtherto provide new and improved relation of means whereby the cutter-bladesof the cutter-head may be jointed during operation of the machine;further to provide a shaving-hood and jointing means for the cutterheadlocated in such relation to each other and to the chip-breaker as topermit simultaneous operation of all said means, and the invention willbe further readily understood from the following description and claims,and from the drawings, in which latter:

liigure 1 is a side elevation of my improved device showing so much of awoodplaning machine as is necessary to illustrate my invention. Fig. 2is a vertical cross-section of the same taken on the line 22 of Fig. 1.Fig. 8 is a front view of the same. Fig. at is a top plan view of thesame, partly broken away; and Fig. 5 is a sectional detail of theclamping means for the cutterhead housing taken on the line of Fig. 8.

I do not in this invention claim the positioning means for thecutter-head housing the same being claimed in a separate application,Serial No. 772598 filed June 9, 1913 divisional hereof, or thechip-breaker and its adjusting and controlling means, the same beingclaimed in a separate application, Serial No. 772110, filed June 6,1918, divisional hereof.

11 represents the main frame of the machine, on which there arestandards 12 having guides 13 thereon. A cutter-head hous- Specificationof Letters Patent.

ing 14 has guideways 15 cooperating with said guides and has movement upand down on said guides. These mideways preferably have a bottom wall 17and an end wall 18, plates 19 being secured to the end walls 18 by bolts20. The cutter-head housing is adjusted to elevation by means ofscrew-rods 25 threaded in nuts 26 in the housing and j ournaled and heldlongitudinally stationary in bearings 27 in the main frame, and havebevel-gears 28 fast thereon.

29 is a cross-shaft journaled in bearings 30 in the main frame.Bevel-gears 31 are fast on the cross-shaft and mesh with bevelgears 28,the cross-shaft being provided with a squared end 32 arranged to bereceived in a suitable socket-wrench for turning the same.

The cutter-head housing is clamped in adjusted position by clamp-screws36 (see Fig. 5), journaled in bearings 37 in the plates 19 and threadedin bearings 38 in the bottom wall 17, passing through slots 35 in theguides 13. A set-nut 39 and a jam-nut 10 are screwed about the outerthreaded end 41 of each of the clamp-screws. The clampscrews are turnedby arms 12 (see also Figs. 1,3 and 1) having splilie-connection with theclamp screws. This splineconnection is shown accomplished by a key .1-3in the clamp-screw received in a spline-groove 4st in the hub 45 of thearm 42.

The arms at the respective ends of the cutter-head housing are connectedby links l6 having articulation with said arms at 17, arms 48 extendingfrom the hubs 15, the arms being connected by a link 19 articulatedtherewith by articulations 50. The arms 48 have hand-grips 51 thereon.

A cutter-head 55 is journaled in bearings 56 in the cutter-head housingor support. it is arranged to carry suitable cuttenblades, instanced bythe cutter-blades 57.

(51 is a chipbreakcr before the cut of the cutter-head, which maycomprise a chipbrcaker foot (32 adjustable on the body (53 of thechip-breaker toward and from the cutter-head. The foot has a toe (34.This adjustment is shown accomplished by providing a guideway (35between the body and foot of the chip-ln'eaker. (See Figs. 2 and 3.) Aset-screw ($6 at each end of the chipbreaker is adjustable in a threadedbearing 67 on a lug (38 on the foot (32 and is locked in ing formed byplates adjusted position by a lock-nut 69, the vend of the set-screwbearing against a lug on the body of the chip-breaker. The chipbreakerfoot is clamped to its body by means of clamp-screws 71 received throughslots 72 in the body and threaded into threaded bearings 73 in saidfoot. Means hereinafter described are provided for limiting approach ofthe toe toward the cutter-head. The chipbreaker has sliding connectionat each end thereof with the cutter'head housing, shown in the form ofguides 75 on the body of the chip-breaker sli'dable in guideways 76 inthe housing, one wall of the said gnideways be- 77 rigidly secured to.the housing by bolts 7 8. The toe 64 of the chip-breaker is providedwith a stock-contacted face 7 9 closely adjacent to its chipbreakingedge, parallel with the plane of the feeding face of the stock-support82 and with a forward end wall 80 parallel to the right line movement ofthe chip-breaker caused by the guides 75 and guideways 76. Thecl'iip-breaker foot has an upwardly slanting stock contacted sole 81arranged to be contacted by the end of stock having a wide range ofvarying thicknesses.

For the purpose of resiliently resisting rising movement of thechip-breaker, I provide double-link yo-kes 91, 92, the doublelink yoke91 comprising the links 93 having a crosspiece 94 integral therewith.The double-link yoke 92 comprises the links 95 having a cross-piece 96integral therewith between the same at one end thereof. The double-linkyoke 91 has bearings 97 at one end thereof, in which journal-bolts 98are 'journaled, the journal-bolts having threaded connection in thebearings 99 of the body of the chip-breaker. The double-link yoke 91further has bearings 100 at its other end, in which journal-bolts 101are journaled, these journal-bolts having threaded connection in theconnected bearing 102 at one end of the double-link yoke 92. The latteryoke further has bearings 103 at the other end thereof, through which arod 104 extends, the rod further having support in the lugs 105 of thecutter-head housing.

111 is apivoted cup in which a spring 112 'is received, the cup being ona cross-piece 113 having trunnions 114 journaled in bearings 115 of thelinks 95. These trunnions are located nearer the pivotal connections ofthe links 95 with the housing than the pivotal'connections between thelinks 95and 93, whereby a minimum of movement of compression andextension of the spring will be caused by the movement of the links 95in accommodating themselves to the changing positions of thechip-breaker.

A screw-rod 116 is threaded into a threaded bearing 117 in thecross-girt 118 of the cutter-head housing and is surrounded by thespring 112 and has a cup 119 adjacent its upper end adjustablypositioned by a setnut 1.20 and a lock-nut 121.

A set-screw 122 is threaded into a threaded bearing 123 in the yoke 92and impinges the cross-girt 118 for limiting the downward movement ofthe chip-breaker, and is locked in adjusted positions by a lock-nut 124.

Means are provided for sharpening or jointing the knives on thecutter-head while the same are rotating at full speed, so as to insure asmooth out being taken off the stock. I have shown this accomplished bymeans of a block 130 of suitable material, which acts upon the cuttingedges of the cutterblades on the cutter-head during their rotation atfull speed, this block of material, such as carborundum or otherknife-sharpening substance, being moved lengthwise of the cutter-headduring such rotation, it be ing understood that the cutter-blades havebeen previously sharpened and approXi-' mately set for causing thecutting edges of the cutter-blades to swing in as true a'circle as canordinarily be effected by the usual setting and gaging mechanisms. Theblock is fastened in a slide 131, being clamped in the channel 132thereof, by a clamp-screw or screws 133. The slide is movable up anddown in a guideway 134 of a carriage 135 by means of an adjusting screw136 journaled in a bearing 137 on the slide and held therein againstendwise movement, and threaded into a bearing 138 onthe carriage, aspring 139 being located around the adjustingj screw between saidbearings for causing recession of the slide from the cutter-head as faras the adjustment of the parts will permit, whereby lost motion is takenout for causing the ointing block to be backed by positive stops,namely, the screw and its bearings, and preventing further recessionthereof during operation and preventing chattering of the block andconsequently insuring that'the cutting edges of the cutter-blades bejointed in true lines at equal distances from the aXis'of rotation ofthe same and preventing any wavy or uneven action upon the cuttingedges. The carriage 135 is slidable back and forth lengthwise of thecutter-head on a slide 140, secured to brackets 141'on the cutter-headhousing, as by means of bolts 142 received through slots 143 in lugs 144of said slide and threaded into the brackets 141, permit ting adjustmentof the slide-with relation to the axis of rotation of the cutterlead fortaking up any wear and insuringaccuracy of result. A rod 1.45 ispreferably releasably secured to the carriage, as by means of a threadedconnection 146, the rod having a handle 147 thereon, by means of whichit may be moved lengthwise of thesli'de during 7 the cutter-head. It maybe placed opposite one of the bearings of the cutter-head when not inuse.

151 is a sl'iavingdiood, which has a month .152, extending preferablyacross the width of the cutter-head, at one side of the cutterhead andlocated at one side of the jointing means ust described. The mouth isarranged at that side of the cutter-head which moves away from thesurface of the stock being planed, instanced as the teed-in side of thecutter-head, -t'or receiving the chips from that side of thecutter-head, and drawing in all the chips made by the Clli'tOP-llfitttl,for preventing the passage of said chips to the jointing mechanism, themouth preferably o 'iening adjacent to the top of the honnet 15E} of thechip-brtniker. "he jointing device is located entirely outside theshaving-hood {or pern'iitting the operation of the jointing devicewithout. action upon or dis arrangement of the hood, the jointing devicebeing separated from the shavings passage of the shaving-hood by one ofthe walls of said hood, while the hood is also removable away from thecutter-head. The action of the shaving-howl, is to take the shavingsfrom each individual blade before it reaches the jointing device,whereby no interrupt ion to the feeding of the board or stock throughthe machine need take place while jointing the knives. The shavings areremoved by a current of air through the hood in the direction of thearrow 0. The shaving-hood preterably opens at one side of thecutter-head, the jointing device being slidable at the other sidethereof.

For conveniently mounting and permitting removal oi. the shaving-hood Iprovide the same with a hook 155, which is received upon the rod 10 1-,and with lugs 156, one of these lugs being at each end of theshavinghood, and arranged to rest upon shelves 1.57 oi? the cutter-headhousing, for positioning the hood with relation to the housing andpermitting the mouth of the hood to be arranged as close to thecutterhc:ul as possible. The hood has telescoping connection 158 withthe pipe 159 oi the blower-system for permitting ready movement of thehood up and down.

My improved device further provides ready means whereby the shaving-hoodand the ointing device are located and operable side by side about thecutter-head, each being independently movable, the mouth of theshaving-hood being further so arranged with relation to the chip-breakeras to permit right line movement of the chip-breaker with relation tothe cutter-head.
